iication.

'tachment is applied to My invention relates to a typewriting attachment for adding machines.

The object of my invention is to provide au attachment for the Standard adding niachines which shall fgive to them the 'advantages of a typewriter without1 in any way interfering .with the normal work oi the adding machine.

-My device is shown attachedto the well known Burroughs adding machine, although I do not confine m self to the use of this type of machine. eretofore it has been necessary, whenever adding or computing is to be done in connection with written explanations, .to use a typewriter, provided with an adding attachment. The diihcuity in this class of machines, the adding machine' predominates, is that the 'typewriter is not so rapidfor listing n'umhers as the adding machine.

My device is especially adapted. to work where the listing of numbers predominates and for this reason the adding machine is left in its normal Working condition with the typewriter attachment for the occasional word of explanation. HeretoiforeV in such machines the attachment has been made either as aseparatev machine, adapted t0 write upon the same platen asv the adding machine or the adding machinefand typewriter have `been built as one Vmachine in which the adding machine is controlled by the Y typewriter keys. With my employ two sets of keys. The typewriter atthe adding machine, but its action is entirely independent of the adding machine. So also is the adding machine entirely independent of the ,typefar as the work is conwriter attachment so attachment cerned, although the typewriting Tn the class embodying the separate machine as a typewriter, which writes upon the same platen.. the position of the keys of the typewriter has made its operation very Specification of Lettera Estant.

when the work of .pression of the adding machine type,

device l' is fastened securely to the adding machine.l

l -diiicult With my device il place the typewriter lreys hetween the operator and the adding machine keys so that he mayreach the ypewriter lieys with least eort, since they are nearer to him than the adding inachine keys, nor does this position o the typewriter keys prevent the operator from sitting at or standing as close to the adding machine as he does sit or stand naturally in the'worlr on the adding machine when nol typewriter attachment is applied to it. l arrange the type hars so as to the. platen when the platen is pushed hack, as it now moves on its pivot to erniit the operator to see the printing ine.' llhis throws the printing line at nearly the top position oi the platen so that the type hars o 'the typewriting attachment may write in the 'same line as the adding machine.

@ne oi' the principal; features of my device is the connection between the working parts oi the addingmachine and the platen of the adding machine, so that the return of the handle oi'` the' adding machine shall always correctly lace the platen in position for the type oi t e writing attachment, and at vtheeame time when a number is to he recorded in the adding machine, the 'forward movement of the handle or other os cillating parts ofthe adding `machine shall nic-ve it to the ext-reine forward position, that is, the printing position of the adding machine. lll`he platen will receive the an the return of the handle or of the adding machine parts to their normal position shall again return, the platen to the printing position for the writing attachment. 1n this way iprerent any possibility of recording on the adding machine with the platen out of position so as to prevent the adding machine type from recording on the platen as l also make itimpossible for the' typewriter to he operated without having. theplaten in position for the writing attachment.

print upon` To these and other ends the invention combined adding and typewriting machine ice having a platen in common with the printing mechanism of both the adding machine and the typewriter, and mechanism operatively connected with the operating-crank of the adding machine or some other movable mechanism thereof, whereby Ythe platen is shifted into pir' ting position relative to the adding Imac, ineprintin mechanism or t e typewriter printing mec anism.

In the drawings furnished herewith Figure l is a side elevation of the Burroughs adding machine, showing my invention applied to it, Fig. 2 is a plan of a fragment of the same, Fig. ,3 is a detail front view of the type .bar mechanism, certain parts of the machine being cut awa on the line 3-,3 Fig. 2, Fig. 4 is a detail cross section taken on line 1 -4 Fig. 2 and Fig. 5 are fra ental side elevations of the type bai' mec anism and its sup rt. Fig. 6 is an elevation showing the plliioten swung forwardly out of typewriting position into position for receiving an impression from the adding machine. Fig. 7 is a plan of the machine. The tpewriter keys are arranged at the sides o the machine; and it will be understood that the type bars at one side are duplicated at the ot er sidevof the machine, asin'the Oliver typewriter. The connections extend along t e sides of the machine rearwardly from the keys to the type bars.

In the drawings, an ad machine known as the Burrou hs mac e 10, is illustrated, said machine -being rovided with the usual keys 11, that are epressed to set Vthe mechanism,v in adding or computing. The machine contains a support 14, for the carriage 15, said carriage being slidably mounted upon the support 14, as usual. The carriage has an oscillato platen supporting frame 15, whichis fdly the remainder of the carriage at 16, whereby it may be moved. into either of two printing positions. lThe frame 15", of said carriage supports the platen 12, in suitable bearings whereby the platen may rotate therein.

Under normal conditions the platen lies in position'to be printed upon by the tytpewriting attachment, and mechanism as been provided for causing said platen to assume the position wherein the printing `mechanism of the adding machine may print upon the platen. Y A simple means for accomplishing this result comprises a connectionbetween the platen or its support and some part of the operating 'mechanism of the adding machine, as for instancethe operating crank 17 whereby when said crank is drawn forward, to record in the adding Amachine and print, the platen is drawn forwardinto'printing position relative to the printing mechanism of the adding machine.

Asshown .in the drawings a link 20, is

crumed upon employed between the platen sup orting frame 15, and the crank 17 one en of the linkfslidingly connectingwith a rod 22, car ried--by the frame and extending parallel with the platen 12, the other end of the link being ivotally connected with the crank 17, at'suc a point in its length, as at 21, that the platen will be moved to the proper position whenever the crank V17, is moved through its arc of movement. The crank 17 is fastened upon a shaft 18, and bears a handle `19, by means of which it may be actuated.

Above the carriage and platen are located the type bars of the ty writing mechanism, and th are supportedxin such manner that when t e typebars are swung down, the type strike upon the u per side of the platen. The typewriting mechanism employed, for the purpose of illustration, is substantially that of the 5 Oliver typewriter, althoug any other suitable mechanism may of course besubstituted in its lace. The type bar frame 23, is supper from the frame 10, of the adding machine as by a bracket 23, which is bolted or otherwise secured to the adding machine frame and the type bars 24, are vpivotally sustained in said type bar. frame in the usual manner.

The typewriter keys 29, are located at the frontend of the machine and are operativel connected with the type bars 24, in suc manner that the said type bars are swung down when the keys are depreed. One

form of connection is shown in the drawin s and will be seen to comprise rock sha ts 28,-'one for. each type key-journaled in bearings 30, secured to thesideof .the adding machine, each rock shaft having a crank 28, engaging with'the t pcwriter key 29, and a crank 27, connecte with a type bar, as for instance by a link 25.

Each type bar is shown as formed with a lug 26, near its lower end, to which the link 25, is pivotally connected, said link extending laterally toward the side of the machine and connecting withv the free end of the crank 27, of one rock shaft. I

Springs 29, may be employed to icturn the typewriter keys and type bars to normal position, said springs being shown as connecting the lower ends of the type keys with the frame 29", in which the type keysare mounted and guided. It is obvious that this A particular construction and arrangement of the type bar operating mechanism is not es sential to the invention broadly considered, as there may be many forms of connections for operatively connecting the typewriter keys with the type bars. y

In the operation of the adding inachne, the usual conditions prevail, .that is, the keys 11, are pressed in such va way as to represent the digits of .the number to be recorded, when the crank 17, is pulled to the forward position by means of the handle 19,-as shown in the dotted lines (Fig. l) and in this way the number is both recorded in the counter of the addin machine and printed upon the platen 12, w ich is brought `to the printing position by means of connection 20.. On the return of the handle, the platenv is forced to its backward position whereby the printing line of the adding machine is caused to register with the printing line of the typewriter, so that in case any explanation or dates or numbers, not to be computed, be written, the type lbars will print upon the platen as in the usual way with a typewriter, since the platen now becomes the typewriter platen. The carriage, which combines the functions of both addingmachine and typewriter, preserves the movements of the adding machinethat. is to say the adding machine carriage may be moved fromy right to left Aor the reverse or the platen may be moved back in order to bring to view the printing line, and said carriage, has added to it the usual t writer escapement and tabulating mechanism (not shown) since I make no claim for any specific escapement'or tabulating mechanism. Should a word or more of explanation ,or' a namebe required in the record, the same is written by using -keys 29, the same as keys are used upon any typewriter when the type bars 24, by means of the rock shafts 28, will-be driven to the printing line as in the usual manner on lany typewriter. .Ishow inthe drawings the particular form of type bar mechanism employed on vthe Oliver ty ewriter, b t I do Vnot confine m self to '-t 40 since the essence, of my invention. consists in the position'of the typewriter keys -with relation to theadding machine keys and the novel means by which the typewriter bars are caused to operate together with the movement of the platen, so that either machine may work with the same freedom-as though it were not connected to the other, and at the same' time the workof the two may be combined in sucha way as to do all of the work or any of the work which may now be rformed by both machines acting indepen ently in succession upon the same sheet. The importance of this work of the two machines in conjunction with each other `can hardly be realized as it not only saves the time and labor of printing upon .the same sheet in one machinev and then transferring it to another, but it avoids the greater disadvantage of the source of error which exists where explanations are to be written for items already listed, or the reverse.

I am aware that various alterations and modifications of this device are ossible without departing from the spirit o my inhaving an oscillatory isl partie ar construction,
